You need a HTML
form, PHP is not needed to have such an URL.
You can use PHP to
use the information in the URL.
See:
http://www.php.net/manual/en/tutorial.forms.php for some (a little terse) information.
Use method="get" instead of method="post" as on that page.
then use $_GET['name'] instead of $_POST['name'] in PHP to use the info from the URL.
